1 Claim.

My present 'invention relates to an improved electrical discharge head that may be employed and adapted for various uses, as for instance, as an applicator or distributer of electrical currents ,5 in therapeutic treatment of the human body, or the heads may be used in opposed pairs, as an anode and a cathode, for distributing and receiving, respectively, an electrostatic field or flux during electrical treatment applied to v'arious commodities, as food products, for enhancing their cooking qualities as well as for eliminating deleterious living agencies therefrom.

In therapeutic treatments it is well understood that a high frequency electrostatic flux or field 115 is very beneficial and possesses healing qualities in high degree, but in suchcases and to secure best results, the electrical force generated by the potential or charge must have high intensity, and the alternating charges to the applicator must have such a period or electrical oscillations in the circuit to the applicator and alternating with required rapidity to cause stimulation of the cell structures being treated. By the utilization of the head of my invention, when used as an applicator, the flux or radiant electrical energy, emanating from a multiplicity of discharge points, which terminate at the outer surface of the applicator, is uniformly distributed. Due to the arrangement of the discharge points on the exterior surface of the applicator or distributer head, the strength or force of the radiated energy is evenly and uniformly distributed over the area treated, thereby insuringmaximum benecial results in therapeutic treatment. l

In the electrical treatment of food products, two of the heads are employed, in opposed pairs, in order that the energy may pass through the product as it is conveyed between the two heads, and in thismanner an intense and evenly distributed field or flux is'created for treatment of the product, far superior to previous etl'orts in this line of endeavor.

The uniform intensity and even distribution of the radiated energy are secured by the novel combinations and arrangements of parts involved in my invention as will hereinafter be more fully set forth and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, o and two of its uses, in which the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a side view of an' applicator or distributer head as used in therapeutic treatments,

and Figure 2 is a sectional view at line 2--2 of Figure 1.

Figures 3 and 4 show a pair of solid heads employed as opposed anode and cathode, for creating an electrostatic flux or ileld in the electrical 00 treatment of food products 81e. parts being broken away to disclose the interior construction of the heads.

Figure 5 is an enlarged, perspective view of a portion of the hollow head. Figure 6 is a face 35 View of a portion of a head slightly modified, and Figure 7 is a sectional detail view at line '1 -7 of Figure 6.

In carrying out my invention I utilize a fiatV base plate 1 of circular shape, and fashioned 70 of suitable insulating material in desired size or diameter. The base plate is provided with an annular edge-flange 2, and screws 2' are employed for securing the back plate to the upper free edge of. the hollow head 3, which, as shown 7 is ofV truncated-spherical shape, and fashioned of any-suitable dielectric material or insulating material. y

Within the hollow head is an electrode 4, formed by the use of an inner sheathing of suitable conducting material, as copper, and the copper sheet or lining is secured in suitable manner within the hollow head.

On the exterior truncated-spherical face of the head is provided a series of concentric, annul'ar grooves 5, moulded or machined in the face to a suitable depth, spaced equidistant apart, and, as shown, the grooves are angular is cross section. The wall of the head is pierced by a multiplicity of holes 6 that extend from the inner face of the 90 head and terminate in the grooves in the outer face of the head, these holes being arranged in planes perpendicular to that part of the inner face and the outer 4face of the head through which the hole passes.

In each of the holes 6 a discharge pin 'I is arranged, said pin being of suitable conducting material and provided with an outer discharge point 8, with the tip of the point approximately flush with exterior face of the head, and the point of course terminates in a groove 5.

In Figures 6 and 7 the annular grooves are omitted, and the holes 6 for the pin terminate in conical recesses 5' inwhich the points 8 of the 105 pin are' located. l

At their inner ends, within the hollow head, the pins pass through openings in the sheetelectrode 4, and the heads 9 of the pins are no welded to the electrode to insure an emcient joint or contact between the discharge pins and centrates the electrical currents that' emanate the electrode.

At the center of the electrode, within the head, is fashioned a threaded socket 9 in which the central stem or conductor rod 10, is threaded, and this conducting rod, which passes through the center of the back plate, is provided with an exterior nut 1l, and terminates in a spherical head or ball 12. A socket-clamp 13 embraces the ball to form a universal jointand the joint may be secured in adjusted position by means of the set screw 14, thereby permitting a wide range of adjustment of the applicator with relation to its support or tubular bar 15.

In Figures 3 and 4 where two solid heads of dielectric or insulating material are indicated as 16 and 17 and employed as a distributer head and a receiving head respectively, between which 'the electrostatic flux or eld is created, a product may be passed betweenthese two elements for electrical treatment as previously mentioned.

The two solid heads are provided with the concentric circles or grooves 5 and the points 8 of the discharge pins terminate in these grooves, and each head is provided with a supporting element as 18 or 19, both of which are electrically connected with the at, circular electrodes 4' fashioned from sheet copper, or similar conducting material.

The exterior or discharge faces of the heads in Figures 3 and` 4, conform, generally to the discharge face of the head'in Figure 1, but when the head 17 is used as a receiving head or ground for the electrostatic eld or flux, its shape may be varied between that shown and the dotted line 20 outlining a flat, circular head.

The head as thus described and illustrated confrom the multiplicity of protected discharge points, to insure an intense ilux. or field that evenly and uniformly distributes the force over the area treated for therapeutic purposes.

When the pair of heads are used in opposition as indicated in Figures 3 and 4, the electro static field or flux of high intensity is uniformly distributed and concentrated between the heads, and the number of pairs of heads employed varies with the purpose of the employment of the heads.

The contour of the exterior face of the head, with the discharge points of the conducting pins terminating approximately flush with the exterior face of the head and located in the grooves or recesses insures a radiation of electrical currents from the head of uniform intensity and of equal distribution, over the area to be treated, and thus the maximum beneficial results are attained.

Having thus fully described ny invention, what I claim as new and desire to secureby Letters Patent isz- An electrical discharge head, having a rounded face and recesses in said face, an electrode forming an inner lining for the head, a multiplicity of conducting pins mounted in the electrode and extending through the head with their ends terminating in the recesses substantially flush with the face of the head,'a back-plate on the head. a conducting rod extending through said plate, and co-acting fastening means on said rod and lining.
